24、 will not occur. Handling and installation of bearings shall only be carried out by qualified personnel whose knowledge and qualifications shall be proved. Bearings shall be handled with care and protected from damage and contamination. If unsuitable for lifting by hand, permanent or temporary attac

25、hments shall be provided to facilitate handling by mechanical means. The bearing installation drawing, specified in clause 4 of this standard, shall be available on site. Unloading of bearings from transport shall be done by means of cranes and elevators which carry the bearings by the lifting devic

26、es provided (elements with loops). Chain blocks with hooks shall be used when lifting bearings by crane or pulley (bridges constructed by incremental launching). If bearings are not installled in the structure immediately after delivery they shall be stored by the user on an appropriate substrate, e

27、.g. on planks, being provided with a protective cover and ventilated from underneath. The interim storage shall be such that the bearings will not be polluted or damaged by exposure to weather (heat, rain, snow or hail) nor by contaminants or other deleterious effects such as ongoing work on site or

28、 traffic on site. 4 Bearing installation drawing A bearing installation drawing showing all the data required for the installation (such as dimensions, levels, inclinations, lateral and longitudinal position, tolerances, qualities of the construction material in the bearing joint, pre-setting of the

29、 bearing as a function of temperature of the structure) shall be prepared. The bearing installation drawing may be combined with the drawing of the bearing system to form a single design document. 5 Inspection after delivery At site, prior to installation, the condition of the bearings shall be insp

30、ected and reported. Special attention shall be given to the following points: a) visible damage, particularly to the corrosion protection (see EN 1337-9). The nature and extent of any damage shall be indicated together with details of any permissible remedial action on the bearing installation drawi

31、ng; b) cleanliness; c) security of the temporary clamping devices; d) conformance to the installation and working drawings if this has not already been established by way of quality control or acceptance inspection; e) marking on the top surface of the bearing and on the type plate as well as markin

32、g of x- and y-axis and, if necessary, of presetting on the faces of upper and bottom part of the bearing, in addition identification of measuring points at rotating gap and eventually sliding gap; f) position of all means used to ensure the exact positioning and installation of the bearings, where s

33、pecified; g) indicating device required for movable bearings in main direction of movement, where required; h) the magnitude and direction of presetting, if specified; i) possibility of readjustment, if provided; j) temporary storage on site (see clause 3). 6 Installation 6.1 General Alterations sha

34、ll only be made to the as-delivered condition of the bearings where specific instructions to do so are given on the installation drawing. Any alterations shall only be carried out by suitably qualified persons in accordance with paragraph 2 of clause 3. If required, the first bearing of a given type

35、 (as agreed between the parties involved) shall be installed in the presence of a qualified agent of the manufacturer. Bearings shall be installed in accordance with the installation drawing in all respects in accordance with the marking on the top surface of the bearing.Page 4 EN 1337-11 : 1997 BSI

36、 1998 1) Including resin mortar. The approximate temperature prevailing in the structure and, in special cases, the variations in temperature at different points in the structure, shall be established and used when necessary to determine any presetting (see annex A). The same considerations apply to

37、 temporary changes in the setting or fixing of the bearings. The setting of the bearings shall be checked after they have become operative. 6.2 Placing of bearings Generally bearings shall be installed on an intermediate bed of mortar which serves as a levelling course. Only elastomeric bearings wit

38、hout outer steel plates may be placed directly on the supporting surface which shall be clean, dry, smooth and level within the tolerances given prEN 1337-3. Where specified, levelling screws shall be used to adjust the position of the bearing. As an alternative, wedges or other suitable devices may

39、 be used. Under no circumstances are rigid areas permitted to be produced underneath the bearing. This can be avoided by removing the temporary supports as soon as the mortar has achieved its required resistance. Alternatively a temporary support consisting of compressive material may be used. Accou

40、nt must be taken in this case of the fact that, due to its incompressibility, elastomeric material will not be suitable for this purpose if it cannot expand laterally. The bearing may: a) be placed on a cambered bed of stiffly plastic mortar in such a way that excess mortar can be squeezed out on al

41、l sides; or b) be bedded by pouring or grouting, using free flowing mortar; care shall be taken for an appropriate ventilation. Bearings with headed studs shall generally be installed using pouring or grouting technics; or c) be bedded such that mortar can be packed underneath. This method is only r

42、ecommended for use where the smaller side length is less than 500 mm. The mortar shall be low shrinkage. If other materials are used their suitability shall be proved. Irrespective of the method used, the bearing shall be supported over its whole area. 6.3 Mounting of superstructure or structural co

43、mponent on the bearing Structural components of in-situ concrete are generally formed directly on the bearing subsequent to its installation. The surface of the bearing and the structural component shall be in direct contact and have no separating layer. Care shall be taken to keep the bearing clean

44、, to avoid damage by wet concrete and to ensured that it can be replaced without difficulty. In the case of precast concrete or steel members, appropriate measures shall be taken to ensure their uniform contact with the bearing. Attachment by welding shall only be permitted in exceptional cases. Any

45、 such welding shall only be carried out by suitably qualified persons in accordance with clause 3. Measures shall be taken to prevent damage by heat to sensitive items such as plastic parts. The corrosion protection system shall be reinstated after welding, where necessary. 6.4 Height correction Sho

46、uld height correction prove necessary, it shall be effected by grouting or packing with fine-grained mortar or similar materials. Height correction with the aid of additional metal plates is only permitted if metal to metal surfaces are machined and if it can be ensured they remain flat until their

47、installation is completed. Consideration shall also be given to the corrosion protection required for the plates. Height correction shall only be carried out by suitably qualified persons in accordance with clause 3. 6.5 Installation tolerances If any installation tolerances as given in other Parts

48、of this European standard are exceeded the structural implications of the error shall be calculated and appropriate action agreed upon. 6.6 Mortar joints 1) The thickness of non-reinforced mortar joints between the bearing and the plinth shall not exceed 50 mm or 0,13 + 15 mm, in millimetres surface

49、 contact area perimeter of contact area whichever is smaller. Furthermore, the thickness shall not be less than three times the maximum aggregate size.Page 5 EN 1337-11 : 1997 BSI 1998 The suitability of the mortar used and the method of placing shall be verified by testing in accordance with the relevant specifications. In the case of cement mortar or cement grout the plinth concrete surface shall be saturated with water prior to installation in order to prevent dehydration. Immediately before the mortar is poured any water remaining on th
